On a 124 chassis, you do not have access to the fan from the dash. To get to the blower motor, you need to remove the trim pieces at the bottom of the windshield, the wiper assembly, the cowl area intake covers,windshield drip rails, and other trim, right behind the firewall.Once all the "plastic stuff" is out of the way, you need to remove the top cover off of the blower assembly. It sounds like alot of work, but is pretty straight forward, and simple. It is a dual fan setup with the motor in the center. It seems like you have something that is getting into contact with a fan.
